摘要
MDA中提出了两种重要的模型:平台无关模型和平台相关模型。PIM是反映系统功能性需求的业务模型,PSM是PIM针对实现技术的映射。对于系统的非功能性需求,如安全性、性能、内存管理和通信等,MDA中未提出明确的模型。借鉴面向方面的编程(AOP)的思想,提出了一种基于UML Profile的"方面"建模表示法,用于在MDA中对系统的非功能性需求建立方面模型(AOM),并在MDA方法中增加模型编织(W eaver)环节,得到功能更为强大的基于方面的MDA开发方法。
Platform-Independent Model and Platform-Specific Model are two important models proposed in MDA. PIM is the business model which reflects functional requirements, and PSM is the mapping from PIM to implementation technology. Models for non functional requirements such as security, functionality,memory management and communication are not given in MDA. An aspect diagram notation is represented based on UML Profile according to Aspect-Oriented Programming concept. The aspect diagram is applied to build Aspect-Driented Model reflecting non-functional requirements in MDA. Model-weaving process is added to MDA, and therefore a more powerful MDA development approach based on aspect is obtained.
